T-12BH7-PSV Vacuum Tube - 12BH7, Classic Series, Psvane
The Psvane 12BH7 is a high quality, medium gain, dual triode with a noval base. With 3.5W plate dissipation per triode, the Psvane 12BH7 is an excellent driver tube and works well in any 12BH7 position. The Psvane Classic Series is focused on the reproduction of popular vacuum tubes found in classic audio equipment. When designing the Classic Series, Psvane collected the most sought-after NOS tubes and analyzed each element of their construction, incorporating the most effective manufacturing techniques to produce stable tubes with excellent sound. Whether used in guitar amplifiers or hifi stereo systems, the Psvane Classic Series vacuum tubes excel in all applications. Psvane has been producing high quality vacuum tubes since 2011. The Psvane team originally formed in Shuguang’s high-end tube division but eventually split off to form their own brand.
$26.95
T-12DT8 Vacuum Tube - 12DT8, Triode, Dual
General-purpose high-mu twin triode of the 9-pin miniature type intended for use as an rf amplifier and as a combined oscillator-mixer in fm tuners. This tube is also useful in a wide variety of applications in radio and television receivers.
$9.90
